Example Embodiment

[0035] The specific structure of the present invention will be further described below in conjunction with the drawings and specific embodiments:

[0036] Reference image 3 As shown in the figure, the present invention mainly includes two parts: a USB receiver and a controller body. When in use, insert the USB receiver into the USB port of the computer and establish a wireless connection with the controller body. The communication adopts 2.4GHz frequency, 10 meters of operating range, 360 degree reception, no directionality.

[0037] Reference figure 1 , Figure 4 As shown in the figure, the USB receiver adopts nRF24LU1 single-chip radio frequency chip, which integrates MCU, USB, 2.4G wireless transceiver, greatly simplifies the circuit, and can be stored in the controller body, which is convenient to carry and not easy to lose.

[0038] Reference figure 2 , Figure 5 , Image 6 , Figure 7 , Picture 8 As shown in the figure, the controller body includes: single-chip microcomputer...

Abstract

The invention relates to a controller pointer positioning method based on a composite MEMS sensor and a controller, and relates to the technical field of wireless sensing control. The controller includes a USB receiver and a controller body; the controller body includes a singlechip, as well as an MEMS sensor, an RF circuit, an EEPROM and keys, which are connected with the singlechip; and the controller is characterized in that the MEMS sensor is a composite MEMS sensor and includes an acceleration sensor and a gyroscope, wherein the acceleration sensor is a triaxial acceleration sensor, the gyroscope is a biaxial gyroscope or a combination of two orthogonal homotaxial gyroscopes, the acceleration sensor and the gyroscope are connected with the singlechip through an A/D converter, the acceleration sensor is used for measuring the linear acceleration of the controller body, and the gyroscope is used for measuring the angular speed of the controller body. The invention solves the problems that a single MEMS sensor is incapable of omnibearing control at any angle, is not flexible to use, and is highly limited; the 360-dregree control is realized; the use is smooth and comfortable; and the operation becomes more freely and flexibly.

Description

technical field [0001] The invention relates to the technical field of wireless sensor control, in particular to a method for locating a pointer of a controller containing a MEMS sensor and improvements to the controller. Background technique [0002] At present, with the rapid development of computer peripheral equipment and people's constant pursuit of fashion elements, a single mouse and presentation controller cannot fully meet people's work needs and life experience. Current desktop mice and wireless mice rely on the limitations of the desktop or the surface of special textured objects to work normally. There are also some trackball mice, but the trackball must be moved when using it, and the pointer movement is not flexible enough. The development and maturity of MEMS sensors have injected new vitality into the field of controllers, and some sensor mice have appeared, making the mouse finally "fly". However, this type of mouse or controller is made of a single accele...
